This term our Triangles maths group is learning to add and subtract numbers by using strategies that are faster than counting on and back. Today they were adding several numbers together by pairing up numbers to make tens, then adding the tens with the leftover ones to get their answers. Before they could use this strategy, they had to know all of the compatible numbers to 10, like 6+4 and 2+8. This is why basic facts are so important to learn.
One game we play to learn our compatible numbers to 10, is frogs and lily pads. One person has 10 frogs and they hide some of them under the lily pad while their partner closes their eyes. Then the second person opens their eyes and checks how many frogs are on top of the lily pad. They need to work out how many frogs are hiding underneath.
